Thanks for the responses. I will def have a backup drive for the files.
My mobo is ASUS P9X79 PRO, it says it allows for RAID. Am I still better off getting a RAID card?
I notice on a lot of RAID cards there is a miniSAS connection (SFF-8088 or 8087) that combines 4 drives on a single cable. When a RAID card advertises being either 6Gbps or 3Gbps, does that imply a data limit for all 4 drives combined? Or does each drive individually get its own data limit, even though they are sharing one cable and one miniSAS?
